Application filed October 5, 1921.

To all whom it may concern;

Be it known that I, Ninns T. ToFTTNe, a subject of the King of Denmark, residing at Bradgate, in the county of Humboldt and State of Iowa, have invented certain new and useful Improvements in Jar Closures, of which the following is a specification.

This invention relates to improvements in jar closures and its object is to provide a sanitary, air-tight, leaf-proof closure of simple construction that is readily applied to or removed from the jar and that is cheap to maiuiitacture. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this application and in which-- Fig. 1 is a fragmentary view of a jar provided with my improved closure.

Fig. 2 is a top plan view of the upper section of the closure.

Fig. 3 is a similar view of the lower closure section.

Fig. 4 is a section. on line 4 4.- oi Fig. 2.

Fig. 5 is a view of Fig. 3 in elevation.

Fig. 6 is a sectional view of the rubber ring employed. Like reference characters denote corresponding parts throughout the several views.

The reference numeral l having the neck 2, the upper part of the neck being formed with the grooves 3 and the lower part with the ribs 4, the grooves and ribs being pitched in opposite directions so that the upper and lower portions of the neck are, in reality, reversely threaded. For the lower portion of the neck I provide a closure section 5 of glass, circular in cross section, and formed peripherally with the groves 6 adapted to register with the ribs 4 of the bottle neck, said section 5 being Formed. with the linger piece 7 positioned in the center of its upper surface.

For the upper portion of the neck denotes a jar I pro- 8 which is of shell-like formation and that is provided with the cross bars 9 at its upper end, the spaces between said bars permitting the insertion of the fingers to turn the closure portion in the jar neck. The closure portion is formed peripherally with the ribs 10 adapted to register with the grooves 3 in the bottle neck,

said ribs 10 being pitched in a direction opposite to that of the grooves 6 in the closl'll'e section An annular inclined lip 11 ruiiiiates the closure section 8 at one end,

The closure section 5 is introduced first into the bottle neclz: and by means of the finger piece Tr it moved into position as far down into the neck as it will go. It may contact with the contents of the jar and in the case oi. preserves and the like it may be caused to compress them, when the jar is full, and force out any air within them. The rubber rinp; 12 is now placed on top of the section 5 and the closure section 8 then introduced into the j ai' neck and moved down until. the lip 11 rests firmly upon said ring. The section 8 cannot turn the section 5 and cause it to work further into the bottle on account of the pitch. of the grooves and ribs 6, 10. The closure is now in operative position, the finger piece 7 eirtending up into the closure portion 8 but not being; of sufficient depth to meet the cross bars 9.

lVhat is claimed is z- In a jar closure, a lower section comprising a solid member termed with peripheral grooves, body oi. said member, a spacer ring; adapted to rest upon said lower section, an upper shell-like section formed with peripheral ribs pitched in a direction opposite to the grooves of said lower section, a lip terminating one end of said upper closure section and adapted to rest upon said spacer ring; and cross bars at the opposite end of said upper section. u

2. In combination with a bottle having a neck formed with rooves and ribs pitched opposite directions, upper and lower closure sections formed respectively with ribs and grooves adapted to register with the ribs and grooves of said jar neck, a finger piece formed upou'the body portion. of one o'lf' said closure sections and projecting into the other section. and a spacer ring between said closure sections. I i

In testimony that I claim. the foregoing as my own I have hereto affixed my signature in the presence of two subscribing witnesses.
